Problem 52921. Easy Sequences 40: Quadratic Congruence
Quadratic Congruence is a modular equation of the form:
.
In this exercise you will be given a vector containing the coefficients of a quadratic polynomial (
), and a modulus base (m). Using these data, create a function that outputs the pair (
), which are the 'primitive' solutions to the quadratic congruence.
For example consider the congruence:
, the solution is
, since:
NOTE: A primitive modulus to base m, can only have values from 0 to
. This is a simplified problem, in which the quadratic polynomials given in the test suite, are all factorable, and the modulus base are all odd primes.
